My tests was on 4PC Win7 32bit and 2 PCs with Win 7 64bit and pg_dump 8.4.7 and 8.4.8 32bit. Behaviour is the same
(everywherethe same db). Now I tested template1, my database without the data and new created database without the
tables- the same result. Encoding I use 1250 because our system Win uses 1250 and UTF 8 made me problems with our
letterswith shapes. Next my test was create new database with UTF8 and backup - same result. 

I tried Application Verifier from MS - output

If it can helps I attach mydb without data.
